While it does not exactly make sense to export empty LDFLAGS in case they are empty already, this shouldn't affect the spkg. the correct place to figure out appropriate flags for the Assimulo build system is its spkg-install file/program (you may want to *append* global LDFLAGS, maybe...). regards felix -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
